I installed ruby 2.6.3 using RVM. later when i try to install rails i am getting following error.
$ gem install rails -v 6.0.2.1
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/local/rvm/gems/ruby-2.6.3 directory.
$ sudo gem install rails -v 6.0.2.1
sudo: unable to execute /usr/bin/gem: No such file or directory
That's because at some point you used sudo to install your rvm. So, the system will require sudo permission to install later gems
When you use command $ sudo gem install rails -v 6.0.2.1, you tell system to use normal directly installed ruby, not via rvm, so it warns you No such /user/bin/gem error
The solution for this is to change ownership of all files in the ~/.rvm directory to current account, as if you're using root account by following command
sudo chown -R $USER ~/.rvm
I am setting up a new system. I'm using rbenv instead of rvm because rvm changes the definition of 'cd' and that's just evil.
I've got the required version of ruby and rails (I think) installed, but bundler is causing problems:
turlingdrome$ gem install bundler

So, I tried using sudo once, and now I think that the permissions are super user... so I'm using sudo. no big deal.
Installing appears to work.
When I try to uninstall, it says it's not installed.
When I try to run it, it finds an executable, but then says it can't find an executable.
I'm using ruby 2.5.3 and rails (I think) 5.2.3.
Rails crashes with:
turlingdrome$ rails -v

which I assume is the same issue.
In case this matters, I'm on a mac.
rbenv works by inserting a directory of shims at the front of your PATH:
~/.rbenv/shims:/usr/local/bin:/usr/bin:/bin
Through a process called rehashing, rbenv maintains shims in that directory to match every Ruby command across every installed version of Ruby—irb, gem, rake, rails, ruby, and so on.
Shims are lightweight executables that simply pass your command along to rbenv. So with rbenv installed, when you run, say, rake, your operating system will do the following:
Search your PATH for an executable file named rake
Find the rbenv shim named rake at the beginning of your PATH
Run the shim named rake, which in turn passes the command along to rbenv
You messed up your rbenv installation.
1) Remove ruby installation outside rbenv
2) rvm implode
3) Clean up your $PATH env variable from ~/.bash_profile or ~/.bashrc
Remove any $PATH reference pointing to ruby, irb, gem or any folder including those bin executable. Consider commenting any $PATH statement from your bash_profile
# export PATH="$HOME/etc/bin:$PATH"
# leave the statement below
# export PATH="$HOME/.rbenv/bin:$PATH
The $PATH variable includes a list of folders:
echo $PATH
home/fabrizio/.rbenv/shims:/opt/android-studio/bin:~/.scripts/bin
if you run gem in your terminal
any .bin executable file included in home/fabrizio/.rbenv/shims or /opt/android-studio/bin is executable from any location in the terminal. When you run gem, the ruby gem command is executed instead of being intercepted from rbenv, because you installed ruby outside of rbenv.
UPDATE BASED ON YOUR FEEDBACK
You must have followed this step when installing ruby 2.5.0 without rbenv so remove from your ~/.bash_profile or ~/.bashrc the following line
PATH="$PATH:$(ruby -e 'puts Gem.user_dir')/bin"
or any other line which is adding /Users/brianp/.gem/ruby/2.5.0/bin to your $PATH, then uninstall ruby with apt.
Read the following information, additionally always check the location where gems are being installed with gem env:
$ gem env home
# => ~/.rbenv/versions/<ruby-version>/lib/ruby/gems/...
if the location from anywhere in the terminal is not under ~/.rbenv/ then you are installing the gems in the wrong locations.
LAST RESORT
Delete the gem folder with rm -rf ~/.gem, a similar approach to this post if you can not remove /Users/brianp/.gem/ruby/2.5.0/bin from your $PATH
SOLUTION FOR YOUR LAST ERROR
This error is caused from installing bundler 2.0
can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)
you need to remove bundler 2.0 and install 1.9.0
Usage of rbenv is a good choice to manage ruby installation on Mac, but it seems that you finished up in a complete mess of broken rbenv/gem/rails/bundler installation and permissions. It it is not worth of fixing it, so I suggest to just get rid of rbenv, remove ~/.rbenv directory and install rbenv with brew again using this guide.
Other ways to check:
Run rbenv-doctor
curl -fsSL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-doctor | bash
Remove ~/.rbenv directory, run rbenv init again and install required version of Ruby
Check that which ruby and which gem points to appropriate location inside ~/.rbenv directory
Things to note:
rbenv and brew, as well as gem do not require sudo, so you should never use it with them
Do not forget to add eval "$(rbenv init -)" in your shell init script, e.g. echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
warning: Insecure world writable dir /Users/brianp/work in PATH, mode 040777
Looks like problem with access rights. Try this:
sudo chmod 755 /Users/brianp/work
Seems to be a permission issue on a folder.
permission denied # rb_sysopen -
/Users/brianp/.rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/bundler-2.0.1/CHANGELOG.md
I'd try to change permissions on the mentioned file / folder using chmod 755 /Users/brianp/.rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/
There are several posts which handle a similar topic, e.g. this.
Try to delete Gemfile.lockand try to install and use bundler again - I have just found that on Github:
Bundler 2 introduced a new feature that will automatically switch between Bundler v1 and v2 based on the lockfile [...] If you do, it can be fixed by installing the version of Bundler that is declared in the lockfile. This bug was fixed in RubyGems 3.0.0 but backports are now being prepared for previous major versions of RubyGems. We’ll let you know when they become available.
Can you try that?
gem install bundler --user-install
I've been running in circles trying to install the 'twilio-ruby' gem in my rails app to no avail. Every time I try to bundle install I receive errors around libxml. Below is a part of the error I'm receiving when I add 'twilio-ruby' to the gem-file and try to bundle install:
Errno::EACCES: Permission denied # rb_sysopen - /Users/George/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/libxml-ruby-3.0.0/HISTORY
An error occurred while installing libxml-ruby (3.0.0), and Bundler cannot continue.
Make sure that `gem install libxml-ruby -v '3.0.0'` succeeds before bundling.
Trying to gem install libxml-ruby results in the error below:
ERROR: While executing gem ... (Errno::EACCES)
Permission denied # rb_sysopen - /Users/George/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/libxml-ruby-3.0.0/HISTORY
Any help that points me in the right direction would be much appreciated.
to install correctly rbenv follow the instructions on github for your operating system (Mac or Linux)
rbenv installation
While to better understand this problem, it is connected to security issues. Mac and Linux are Unix based system, where the user logs in and can execute commands on his home directory ~/<user>. If you try to execute a command to run a script in another directory like the root directory / or /bin, you will get an authorization error and you will need to run the command with sudo that stands for system user do.
For this reason, with linux you configure the ~/.bash_profile file
Add ~/.rbenv/bin to your $PATH for access to the rbenv command-line utility.
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
Ubuntu Desktop note: Modify your ~/.bashrc instead of ~/.bash_profile.
Zsh note: Modify your ~/.zshrc file instead of ~/.bash_profile.
so that those command irb, gem, rake, rails when executed from the user they:
Search your PATH for an executable file named rake
Find the rbenv shim named rake at the beginning of your PATH
Run the shim named rake, which in turn passes the command along to rbenv
explanation of shims in rbenv
You can also solve easily this problem by running the command with sudo, but it is not reccommended, as you can read also from the below post where they have the same problem but with rvm,
Why do I get a "permission denied" error while installing a gem?
I am trying to install rails , in order to install cocoapods but I am having some trouble with permissions.
I tried $ $sudo chown -R username /usr/ but operation is now allowed.
Username-MacBook-Pro:~ username$ $sudo gem install rails
Building native extensions. This could take a while...
ERROR: While executing gem ... (Errno::EACCES)

You should not install rails with the sudo command for two reasons:
I made this mistake in the past and then I had issues when installing and using other gems because of inconsistencies with permissions. It might very likely cause you the same trouble.
The concern of whether or not to install rails with the sudo command is addressed and well explained in a different post: 'sudo gem install' or 'gem install' and gem locations
The reason why installing gems with sudo is worse than just gem install is because it installs the gems for ALL USERS as root. This might be fine if you're the only person using the machine, but if you're not it can cause weirdness.
I recommend that you install rvm first and then rails. Here is a great tutorial that walks you through the process: http://railsapps.github.io/installrubyonrails-mac.html
I was trying to install ruby on rails in mac.
I have Xcode and gcc compiler installed. When i tried to install git, it showed me the following error:
$:~ gem install git
$ ERROR: While executing gem ... (Errno::EACCES)
Permission denied - /Library/Ruby/Gems/1.8/gems/git-1.2.5
I changed the permissions of my 1.8 and gems directory. Still it is showing the same error. Any suggestions?
Have you tried with sudo? Try sudo gem install git.
